[Ffmpeg-devel] Need help on encoding to .jpg

[Cool_Zer0]

Hi there.

I'm trying to decode a .jpg to resize it and then encode it again to .jpg.

The logs are the following:
[Level:0]    Compiler did not align stack variables. Libavcodec has been 
miscompiled
and may be very slow or crash. This is not a bug in libavcodec,
but in the compiler. Do not report crashes to FFmpeg developers.

The piece of code that generates this code is on attachment...

The result is a full green frame with the correct dimensions... I've 
analyzed the file with a HEX editor and it looks good on the header but 
on the image part is all green...
Other thing (that may be a hint): In the logs nothing about the encoding 
appears... Isn't that weird?



I appreciate any help...



Thanks
